Yield Rate / Manufacturing Consistency

Yield is the share of units that pass inspection; consistency is how little individual units differ from each other.

Yield rate is the proportion of manufactured units that pass inspection on the first try; manufacturing consistency is how much individual units of the same model differ from each other in dimensions, motor parameters, sensor readings, and joint zero positions, among other things. Both are key thresholds on the path from prototype to mass production: low yield drives up cost, while poor consistency means a policy tuned to work on one robot may fail on another unit of the exact same model, and also raises calibration and after-sales costs. The consistency of core components — joint modules, dexterous hands, and reducers — draws particular attention.

ExampleIf torque constants vary too much between motors in the same batch of joint modules, control parameters tuned on one robot can produce distorted motion when moved to another.
